MASK FOR INI-IALATION.

- Speccation of Letters Patent. Patented Sept. 20, 1921.

Application filed March 17, 1920. Serial No. 366,539.

To all whom may concern.'

Be it known that I, 1vViLrnED J. JANDRON, a citizen of the United Statesresiding at Minneapolis, in the county of llennepin and State ofMinnesota, have invented a new and useful Mask for Inhalation, of whichthe following is a specification.

My invention relates Vto a mask and mask holders for inhalation ofchloroform or for medicated oil in cotton, as is often used in diseaseslike bronchitis, asthma or other chest troubles.

The object of the invention is to provide a convenient, and easilyapplicable device for said several purposes, and to make the deviceattachable to the head of the patient so it will always remain in theposition it may be set relative to the nose and mouth of the patient.

In the accompanying drawing:

Figure 1 is a side view of a human head with my improved device mountedon same in position for use. Fig. 2 is a top view of the device shown inFig. 1 with the head omitted and the mask holder proper turned upward toabout horizontal position. Fig. 3 is an enlarged cross section on theline 3 3 in Fig. 2.

Referring to the drawing by reference numerals, a head gear or hood iscomposed of a metal strip or band 4 curved to encompass the front andsides of the head 5. Detachably secured by hooks 6 upon the inner sideof the band is a cushion 7 the rear ends of which are provided withribbons 87 for tying the band snugly about the head.

Pivoted at 9 to said band are the legs of an arch 10, having at itsmiddle a slit 11, through which extends the rear end of a curved bar 12,which is provided with small embossments 13 to make the bar staywherever it is set in the slit 11, by engaging one of the edges ofthe'slit.

The front end of the bar 12 is pivoted at 14 to an arm 15, which isslidably Aand frictionally-held in a guide 16 fixed at the front oftheband 4. 1

Frictionally-held by a pivot screw or bolt 17, having a nut 18, are theends of two band metal loops or yokes 19 and 20. Likewise frictionallyheld between the ends of said yokes is an arm 21, upon which is slidablyand frictionally held a small metal box 22, having a removable cover 23with perforations or other foraminous portion 24,

while the bottom of the box has several perforations 25. l

Pivoted to the yoke 19 are the legs of two wire arches 26-27, which maybe folded to the yoke or raised up therefrom until their tops cross andengage each other by means of curves 28 formed'on them.

I n the operation of the device the hood is adjusted and secured on thehead of the patient as shown in Fig. 1. If the gas or aroma of medicatedoil is to be inhaled, ab* sorbent cotton or a similar agent is saturatedwith the medicine and placed into the box 23 and the box swung so closeto the face of the patient that the air thus medicated is yoke is thenbrought down so that the cloth is held between the two yokes 19-20 andforms a bowl upon which the chloroformy is sprinkled. The bowl is thenswung at the pivot 17 and held by friction in said joint at any desiredproximity to the face of the patient.

That I claim 'is:-

1. In a device of the kind described, a head gear adapted to be securedon a persons head and having at its front a depending arm, two yokespivotally clamped on the end of said arm and adapted to hold a'clothpinched between them, one of the yokes having arched wires by which toform the cloth into a bowl, a special arm detachably secured on thepivot with the yokes, and a perforated box detachably held on thespecial arm and adapted to hold a medicated element.

2. In a device of the kind described, a head gear comprising a metalband adapted to go about the front and sides of the head, a cushiondetachably secured aty the inner side of the band and having at itsrearward ends means to be secured across the back of the head, an archextending from side to side over the top of the head and having its endspivotally secured to the band, and a curved bar adjustably held to themiddle of the arch and extending down the front of the head, and havinga vertically slidable 3. The structure specified in claim 2, saidconnection with the front part of the band, curved front bar having apivot joint above the sldahle portion of said bar having its the band,to enable lateral adjustment of 10 front end extended forwardly anddownthe part holding the medicated element. Wardly and adjustablyattached to the part In testimony whereof I affix my signature.

of the device carrying the anesthetics or other medicated element.WILFRED J. JANDRON.
